Two teenage girls have been charged following an alleged attempted robbery at a Wagga Wagga service station last week.

About 7.45pm on Wednesday 4 May 2016, two people, allegedly armed with knives, entered the Tobruk Street Ashmont premises and threatened the attendant.

The male employee was assaulted by one of the offenders but was able to fight them off.

The pair, who had concealed their faces during the incident, left the store empty handed.

The employee, who was not injured during the robbery, was able to raise the alarm.

A crime scene was established by officers from Wagga Wagga Local Area Command and was later examined by specialist forensic officers.

About 4.30pm today (Friday 13 May 2016), following investigations, two 17-year-old girls attended Wagga Wagga Police Station, where they were arrested.

One of the girls was charged with attempted robbery whilst armed. The other was charged with principal in the second degree to attempted robbery whilst armed.

Both girls were refused bail and are due to appear at Children’s Court tomorrow (Saturday 14 May 2016).
